Procedure

3-(4-Hydroxy-2,2-dimethyl-3,4-dihydro-2H-chromen-6-yl)-2-methyl-5-{[2′-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}-6-propylpyrimidin-4(3H)-one (1.0 g) was dissolved in acetonitrile (10 mL), and concentrated hydrochloric acid (1.0 mL) was added dropwise at 0° C. The reaction mixture was stirred at room temperature for 30 min. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous sodium hydrogen carbonate solution and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound (0.82 g, 76%) as a colorless solid.
